Post-processing of large castings, large foundry processing manufacturers can use liquid sandblasting to clean the oxide scale and residue on the surface of the casting, which can not only remove impurities, but also play a role in polishing and improving the surface finish of the casting; Use grinding wheels, abrasive cloths, sandpaper and other abrasives to remove impurities such as burrs, protrusions and oxide scales on the surface of steel castings, so that the surface is smooth. In addition, methods such as mechanical, electrochemical and chemical polishing can further improve the gloss and corrosion resistance of castings.

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.
